Modification of the braking torque
The braking torque can be modified by using different quantity and types of springs. Proceed as
follows :
Remove the casing, the fan and the protective band.
Dismount the release lever, if present.
Unscrew the hexagon nuts and move the electromagnet backward of approximately 50
mm.
Modify the combination of the springs and verify their symmetrical arrangement.
Reassemble the brake keeping a minimum interfere, according to what indicated in
paragraph Controlling, adjusting and replace the brake.
Reassemble the release lever, if any, (see Assembly of the manual releasing device)
9.5
Assembly of the manual releasing device
Screw the two stud bolts tight into the disk pusher by
gluing
them, in case, with
Loctite. Insert the elastic plug into the electromagnet.
Arrangement of the release lever. If the manual releasing device is provided with the
stopping device, insert the straight roller. This roller is not present in the manual release
with automatic return pattern.
Screw the adjustment nuts until the end play between the flat conical springs and the
release lever is between 1.5 and 2mm.
Reassemble the fan and the casing. Screw either the hand lever of the release device
with automatic return or the grub screw of the release device equipped with stopping
device.
ATTENTION:
With the stopping device, the rotor gets engaged when a certain
resistance to the screwing of the grub screw is sensed (2). In the
automatic return system, to release the rotor, just operate with your
hand the lever towards the fan. In both cases do not force,
otherwise the disengaging lever could be damaged.
9.6
Replacement of the braking disc
When the brake disk has been worn down to a minimum thickness of 9 mm, it must be
replaced. The new
brake
disc must by no means get in contact with grease or oil!
